The VAUDE Discover and Aqua pannier series are equipped with the technically advanced Hard Back Pro made from hardwearing plastic. The back of the bags and the edges are completely covered by this plate. It helps make the bags extremely abrasion and impact resistant, and protects the edges from being beaten down. This also includes the gear rack – cross bars are no longer a problem: the unique lower hook with 360° mobility makes it possible to attach the bags to any gear rack. It also prevents the loaded bags from swinging back and forth on uneven terrain. Bags featuring the Railhook 360° are symmetrical and can be attached to either side of the bike.
